Freezable Lunch or Snack Bag – Ice Cream Truck No Ice Packs Required This Freezable Snack Bag keeps anything you pack cooler, longer. Small but mighty, this mini cooler is sized just right for kid's meals and adult snacks. It has a patented freezable gel built permanently into its lining and the entire bag freezes to keep contents cool. The gel-lined walls chill a small meal or snacks and a drink for up to 10 hours (depending on external temperature). While other bags merely insulate, a frozen Lunch Bag actually creates cold, eliminating the need for melting ice or bulky gel packs. This Bag keeps food cooler five times longer than other coolers which allows you to pack healthy foods such as: yogurt, milk, fruits and veggies. Uneaten food comes home still fresh and goes back into the refrigerator for the next day, which reduces waste and saves you money. Fold the Freezable Lunch Bag flat and store it in the freezer overnight (12 hours) to freeze completely for maximum performance during use. The Zipper closure locks in cold, dry air and a buckle handle easily clip onto totes, backpacks or strollers. These are made from food-safe, nontoxic poly canvas and are PVC, BPA, phthalate and lead free. Simple Care: interior wipes clean, spot clean exterior. Not machine or dishwasher safe. The Freezable Snack Bag measures 8.25 Inch tall, 8 Inch wide and 3.75 Inch deep while open and fits easily into backpacks and gym bags.
